FexNi100-x thin films were deposited on conductive (Cu) and non-conductive (Pd activated glass) substrate using an electroless, polyol method. The stoichiometry of film composition, as compared to the precursor concentration, strongly depended on the substrate position. When the substrate was immersed in the refluxing solution, Fe-deficient films were deposited. However Fe-rich films were synth...

As plating proceeds, both nickel and hypophosphite ions are consumed. These deficiencies can be corrected by adding nickel and hypophosphite salts. However, as the byproduct phosphite accumulates, the quality of the deposit deteriorates. At some point the bath must be discarded and replaced-a practice that is expensive due to the cost of purchasing a new solution and disposing of the old one. T...

Abstract Through a sol-gel method, honeycomb-like Na 3 V 2 (PO 4 ) /C cathode material for sodium-ion batteries was synthesized from spent electroless nickel plating bath. The obtained exhibited excellent electrochemical properties, with the initial discharge capacity of 108.3 mAh·g −1 at 0.2 C and retention 99.3% after 300 cycles, which comparable to that powders prepared chemical reagents. Th...

in this paper, the hydrogen embrittlement of the high strength cr-si spring steel with after zn-12%ni electroplating, have been evaluated. slow strain rate test with 3.34 × 10 -6 sec -1 strain rate was performed, and the hydrogen embrittlement index of the different samples was calculated. the effect of shot peening before plating and the baking after plating and also the effect of applying a n...

The Ni-B-P alloy coatings were made autocatalytically (electroless) using an alkaline plating bath with nickel chloride hexahydrate (NiCl2.6H2O) as the source of nickel ions, sodium borohydride (NaBH4) and sodium hypophosphite (NaH2PO2) as reducing agents and source of boron and phosphorous ions, respectively. The effects of bath concentrations on the plating rate, composition of coating, surfa...
